Question
Two plane mirrors are placed perpendicular to each other. A ray of light strikes the first mirror and after reflection from the first mirror it falls on the second mirror. Assuming that the final reflected ray is in the plane of the incident ray, the final reflected ray emerges:

Solution
The correct option is B Parallel to the original ray
From the figure, it is clearly understood that the ray is emerging out parallel to the original ray. It is valid only when the plane of the final reflected ray and the incident ray are in the same plane.
